Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories and relates to a rear balancing clamp assembly. Background Art

[0002] In order to achieve the steering of the car, a steering system is provided in the car, which includes a steering gear, a steering shaft, a tie rod, a stabilizer bar, a balance bar, a steering arm, etc. One end of the rear axle balance bar is connected to the frame, and the other end of the rear axle balance bar is connected to the shock absorber.

[0003] For example, a rear axle balancing rod for an automobile disclosed in Chinese patent literature [application number: CN201120185260.2, publication number: CN202071657U] includes a slender rod body, one end of the rod body is provided with a spherical shell connected to the frame, and the other end of the rod body is provided with a fork joint connected to the shock absorber. The fork joint is U-shaped and includes two parallel connecting arms and a connecting bridge located between the two connecting arms.

[0004] The fork joint is a sheet metal component formed by bending steel plates, which has low structural strength. To improve the structural strength of the fork joint, a reinforcing rib is usually welded to the inner side of the fork joint bridge. However, since the rod body and the outer side of the fork joint bridge are also welded together, the double welding of the fork joint bridge is prone to large welding stress and deformation, which reduces the structural stability of the fork joint. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to propose a rear balancing clamp assembly, which solves the technical problem of how to improve the structural stability of the rear balancing clamp assembly.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A rear balancing clamp assembly includes a balancing rod, the lower end of which is connected to a U-shaped clamp, the clamp including a connecting bridge arched in an arc shape toward the balancing rod and connecting arms connected to the left and right ends of the connecting bridge and in a straight shape, characterized in that the clamp is forged as a whole from a metal material, an upwardly protruding hexahedral mounting platform is integrally provided on the upper surface of the connecting bridge, a socket is provided on the top surface of the mounting platform, the lower end of the balancing rod is inserted into the socket and fixed, the left and right side surfaces of the mounting platform are inclined from bottom to top toward the direction close to the balancing rod, and the front and rear side surfaces of the mounting platform are parallel to the balancing rod.

[0008] The forged clamp not only has a greater thickness than the fork joint of the sheet metal, but also can retain better metal streamlines, which is beneficial to improving the structural strength of the U-shaped clamp. A protruding hexahedral mounting platform is integrally provided on the upper surface of the connecting bridge, and the front and rear sides of the mounting platform are arranged in parallel, while the left and right sides of the mounting platform are arranged at an angle, which can increase the thickness of the connecting bridge and further enhance the structural strength of the connecting bridge. Moreover, the left and right sides of the mounting platform are inclined from bottom to top toward the balance bar, and the front and rear sides of the mounting platform are arranged parallel to the balance bar. The mounting platform has a small upper and large lower structure, which is easy to form during the forging process and reduces the damage to the forged metal streamlines caused by machining. At the same time, the mounting platform is protruded to a certain height, so that the socket is formed to a certain depth, thereby providing a larger bonding surface area between the balance bar and the wall of the socket hole, thereby improving the connection stability between the balance bar and the clamp. Therefore, the present rear balancing clamp assembly improves the stability of the structure.

[0009] In the aforementioned rear balancing clamp assembly, the front and rear sides of the connecting bridge are arranged in parallel, the front and rear sides of the mounting platform are both parallel to the front side of the connecting bridge, and the distance from the front side of the mounting platform to the front side of the connecting bridge is equal to the distance from the rear side of the mounting platform to the rear side of the connecting bridge. The top surface of the mounting platform is perpendicular to the balancing pole, and the left and right sides of the mounting platform are symmetrically arranged relative to the balancing pole. This creates a symmetrical structure for the mounting platform on the connecting bridge, which helps improve the structural strength of the clamp at the connecting bridge, thereby enhancing the structural stability of the rear balancing clamp assembly.

[0010] In the aforementioned rear balancing clamp assembly, each of the two connecting arms has a protruding connecting platform integrally formed on its opposing sides. The lower surface of the connecting platform is flush with the lower surface of the corresponding connecting arm, and the upper sides of the two connecting platforms are connected to the left and right ends of the connecting bridge, respectively. The provision of the connecting platform increases the thickness of the connecting arm, improving its structural strength, thereby enhancing the stability of the rear balancing clamp assembly.

[0011] In the aforementioned rear balancing clamp assembly, each connecting platform is provided with a connecting hole that passes through the connecting platform in the vertical direction. The connecting hole is used to pass a bolt through to facilitate connecting the rear balancing clamp assembly to the shock absorber.

[0012] In the aforementioned rear balancing clamp assembly, the outer surface of each connecting platform is a conical cylindrical surface with a smaller diameter at the top and larger diameter at the bottom. This truncated cone shape of the connecting platform, which is smaller at the top and larger at the bottom, facilitates forming during the forging process, reduces machining damage to the forged metal flow lines, ensures the structural strength of the clamp, and thus improves the structural stability of the rear balancing clamp assembly.

[0013] In the above-mentioned rear balancing clamp assembly, the left and right side surfaces of the mounting platform are respectively connected to the upper surfaces of the two connecting platforms, which can improve the overall structural strength of the clamp and help improve the structural stability of the rear balancing clamp assembly.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] In this rear balancing clamp assembly, a mounting platform and a connecting platform are provided on the clamp block, which improves the structural strength of the clamp block. At the same time, the balance bar is inserted into the socket of the mounting platform, which improves the stability of the connection between the clamp block and the balance bar, thereby improving the structural stability of the rear balancing clamp block assembly.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1 As shown, a rear balancing clamp assembly includes a balancing bar 1, a bushing 2 or a ball joint connected to the upper end of the balancing bar 1, and a U-shaped clamp 3 connected to the lower end of the balancing bar 1. The clamp 3 is integrally forged from a metal material, such as 45-gauge or 35-gauge medium carbon steel.

[0022] like Figure 1As shown, the clamping block 3 includes an arc-shaped connecting bridge 3a that arches toward the balance bar 1, and straight connecting arms 3b connected to the left and right ends of the connecting bridge 3a. An upwardly projecting, hexahedral mounting platform 3c is integrally formed on the upper surface of the connecting bridge 3a. The mounting platform 3c has a top surface and four side surfaces, and its bottom is integrally connected to the connecting bridge 3a. A vertical insertion hole 3c1 is formed on the top surface of the mounting platform 3c, into which the lower end of the balance bar 1 is inserted and secured. The left and right sides of the mounting platform 3c are inclined upward toward the balance bar 1, and the front and rear sides of the mounting platform 3c are parallel to the balance bar 1. The insertion hole 3c1 is a blind hole, with its lower portion extending into the connecting bridge 3a. The lower end of the balance bar 1 is secured to the insertion hole 3c1 by an interference fit. The presence of the mounting platform 3c increases the surface area of ​​the connection between the two, making the connection between the balance bar 1 and the clamping block 3 more stable. Alternatively, the lower end of the balancing pole 1 is inserted into the insertion hole 3c1, and the outer side of the balancing pole 1 is welded to the top surface of the mounting platform 3c. The setting of the mounting platform 3c can make the welding point away from the connecting bridge 3a, reduce the welding stress and deformation of the connecting bridge 3a, and make the connecting bridge 3a structure stable. Figure 2 and Figure 3 As shown, the front and rear sides of the connecting bridge 3a are parallel, and the front and rear sides of the mounting platform 3c are both parallel to the front side of the connecting bridge 3a. The distance from the front side of the mounting platform 3c to the front side of the connecting bridge 3a is equal to the distance from the rear side of the mounting platform 3c to the rear side of the connecting bridge 3a. The top surface of the mounting platform 3c is perpendicular to the balance pole 1, and the left and right sides of the mounting platform 3c are symmetrically arranged relative to the balance pole 1. The front and rear sides of the mounting platform 3c are also symmetrically arranged relative to the balance pole 1.

[0023] like Figure 1 As shown, the two connecting arms 3b are integrally provided with a protruding connecting platform 3d on the opposite sides. The lower surface of the connecting platform 3d is flush with the lower surface of the corresponding connecting arm 3b. The upper sides of the two connecting platforms 3d are respectively connected to the left and right ends of the connecting bridge 3a. Each connecting platform 3d is provided with a connecting hole 3d1 that passes through the connecting platform 3d in the vertical direction. Figure 2 and Figure 3 As shown, the outer side surface of each connecting platform 3d is a conical cylindrical surface with a diameter that is smaller at the top and larger at the bottom. The left and right side surfaces of the mounting platform 3c are respectively connected to the upper surfaces of the two connecting platforms 3d.

[0024] The forged clamp 3 retains good metal streamlines, which helps improve the structural strength of the U-shaped clamp 3. The protruding mounting platform 3c integrated into the upper surface of the connecting bridge 3a increases the thickness of the connecting bridge 3a, further enhancing the structural strength of the connecting bridge 3a. The protruding connecting platform 3d integrated into the connecting arm 3b increases the thickness of the connecting arm 3b, further enhancing the structural strength of the connecting arm 3b. Furthermore, the mounting platform 3c is a structure that is smaller at the top and larger at the bottom, while the connecting platform 3d is a truncated cone-shaped structure that is smaller at the top and larger at the bottom. This facilitates forming during the forging process and reduces damage to the forged metal streamlines caused by machining. Furthermore, the protruding mounting platform 3c is provided at a certain height, allowing the insertion hole 3c1 to form a certain depth, thereby increasing the bonding surface area between the balancing rod 1 and the wall of the insertion hole 3c1, thereby improving the connection stability between the balancing rod 1 and the clamp 3. Therefore, the present rear balancing clamp assembly has improved structural stability.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
